r600g: don't change the order of writes in merge_inst_group

Merge may produce incorrect order of operations for r600-eg:

x: inst1 R0.x, ... ;  //from current group
...
t: inst0 R0.x, ... ;  //from previous group, same destination

Result of inst1 will be lost.

So compare destinations and don't allow this.
